SPECIFICATION forming part of Letters Patent No; 605447, dated June 7, 1898. Application filed January 12, 1897. Serial No. 618,982. (No model.)

To all whom it may concern.-

Beit known that I, GEORGE W. KORTRIGHT, a citizen of the United States, residing at Sioux City, W'oodbury county, State of Iowa, have,

invented certain new and useful Improvements in Telescopic Clamps; and I do hereby declare that the following is a full, clear, and exact description of the inventiomwwhich will enable others skilled in the art to which it appertains to use the same.

My invention relates to an improvement in clamps, one section drawing squarely against the other, forcing the inside in and the outside out, forming a clamp between the two sections to be clamped together, also forming a lock-nut on top. As the inside section tightens the nut is forced down, as would be necessary on the handle-bar of a bicycle. I attain these objects by themechanism illustrated in the accompanying drawings, in which- Figure l is a central longitudinal sectional view through the clamp. Fig. 2 is an end View.

D is the main or inner case, and C the nut threaded on the top end of the inner case.

E E E are the slots cut into the inner case to allow same to contractwhen the outer wedge Bis forced down by the nut C, the outer section B being also slotted to correspond with slots E E E, allowing it to spread at the same time the inner case contracts, forming a solid joint outside and in.

G is a cap fitted over the outer tubing K and on which the lian ged shell B rests.

What Ijclaim as my invention, and Wish to secure by Letters Patent, is-

1. In ahtelescopic clamping device, the oom- `bination of an outer tubular member, a ring fastened `inside its end, an inner tubular Aslotted clamping member having a beveled end, the cylindrical portion of shell B slitted and fitted about the contracted portion of shell D, and the tightening-nut threaded on "the upper end of the inner shell and bearing against the iiange of the outer shell, as shown and described.
